Specific embodiment
In the description of the present invention, it is to be understood that, the orientation or position of the instructions such as term "front", "rear", "left", "right"
Setting relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and simplification of the description, rather than
The device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot
It is interpreted as limitation of the present invention.
Combined with specific embodiments below, the contents of the present invention are described in further detail, Fig. 2, Fig. 3 and Fig. 4 points
Do not show the stereoscopic schematic diagram of the stapler in the present invention with anastomosis staple and nail anvil forming tank automatic contraposition device and open,
The main view of two states is closed, is mainly made of several parts such as nail bin 11, nail bin frame 12, nail anvil 2 and adapters 3, wherein
Holding tank 122 (as shown in Figure 6) is provided on nail bin frame 12, it is whole to form one for putting, fixing above-mentioned nail bin 11
Body is named as the first assembly 1 from the aspect of the convenience of subsequent descriptions.First assembly 1 is opposite with nail anvil 2
And it sets.It is provided with nail forming tank 22 (as shown in Figure 8) on nail anvil 2, correspondingly, is evenly equipped with nail position in the opposite face of nail bin 11
111 (as shown in Figure 7).Adapter 3, nail bin frame 12 and nail anvil 2 are articulated as one by means of pin shaft 4.In the first assembly 1
And pin hole compatible with pin shaft 4 is offered on nail anvil 2, and the two is clearance fit.It is fixed to be provided on the first assembly 1
Position protrusion 121, correspondingly, offers positioning groove 21 compatible with positioning protrusion 121 on nail anvil 2.In this way, in reality
In operating process, when exciting to stapler, nail bin 11 carries out rotation around the central axis of pin shaft 4 relative to nail anvil 2 and closes
Resultant motion, in the process, positioning protrusion 121 can be automatically imported in positioning groove 21 (as shown in Figure 5), at the same time,
Force nail bin 11 relative to nail anvil 2 in left-right direction and front-rear direction carry out adaptability adjustment of displacement, ensure that nail position
Contraposition accuracy relative to nail forming tank.
In general, from the aspect of for manufacture convenience and processing cost, above-mentioned positioning protrusion 121 is preferably disposed on
On nail bin frame 12 (as shown in Figure 6), formed by the side wall of above-mentioned holding tank 122 is downward.It should be noted that can also
Positioning protrusion 121 is arranged in (not shown) on nail bin 11 as the case may be.
It being required to meet operation, nail bin frame 12, nail bin 11 and nail anvil 2 are both needed to be provided with biggish Length x Width ratio,
Thus, it is desirable that three is in articulated position assembly precision with higher, when fit-up gap is overproof, easily causes nail bin 11 opposite
Front and back occurs in nail anvil 2 and biases phenomenon, and with the increase of lengthwise dimension, bias is also gradually increased.On solving
Technical problem is stated, anti-deflection can be provided between the first assembly 1 and nail anvil 2 and abuts against portion 5 (as shown in Figure 6), thus
Under the premise of ensuring 2 assembly precision of nail bin frame 12, nail bin 11 and nail anvil, each component own dimensions precision is wanted in reduction
It asks.Specific embodiment is recommended as follows: anti-deflection abuts against portion 5 and is designed as abutting against 51 form of boss, before being set to nail bin frame 12,
Lateral wall afterwards, and (as shown in Figure 6) is arranged around its own pin hole.It should be noted that abut against boss 51 generally by
The direct extension of forward and backward side wall of nail bin frame 12 forms, and the control of its thickness value is in 0.5-1mm.Certainly, abutting against boss 51 also can be excellent
It is selected as resilient rubbber cushion, is bonded in 12 (not shown) of nail bin frame by means of glue.
It should be noted that a kind of remodeling as above-mentioned technical proposal, the above-mentioned boss 51 that abuts against can also be according to specific
Situation is set to the forward and backward inner sidewall of nail anvil 2, is arranged (not shown) also around its own pin hole.
Furthermore it can also will be provided with guiding surface on positioning protrusion 121, in this way, being conducive to the importing of positioning protrusion 121
In positioning groove 21, consequently facilitating nail bin 11 is relative to progress adaptability position adjustment in 2 rotary course of nail anvil.
In general, the pin hole being opened on the first assembly 1 is preferably arranged to round hole, corresponding, is opened in nail anvil 2
On pin hole be set as kidney slot, extended along left and right directions, it is ensured that nail bin 11 relative to nail anvil 2 have it is enough adjustable
Pitch from.Certainly, another transformation as above-mentioned technical proposal, the pin hole being opened on nail anvil 2 also may be configured as round hole,
Corresponding, the pin hole being opened on the first assembly 1 is set as kidney slot, is equally extended along left and right directions.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
